Specification of Letters Patent.

Patented Oct. 23, 1917.

Application filed July 18, 1917. Serial No. 181,305.

To all whom it may concern:

Beit known that I, CLARENCE Manson, a citizen of the United States, residing at Emmons, in the county of Freeborn, State of Minnesota, have invented certain new and useful Improvements in Elevated-Carrier Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in litter or manure carriers, used in barns, stables, and the like places.

The principal object of the present invention is to provide a novel and simple device for holding the carrier from movement on the cable while the carrier is being loaded.

Another object is to provide a brake device which can be quickly and easily thrown in one direction for engagement with the cable to hold the carrier against movement, and in the opposite direction for rolling engagement with the cable while the carrier is in motion.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a portion of an elevated carrier and cable on which it ,runs, showing my improved brake in connection therewith, the brake being inoperative.

Fig. 2 is side elevation of the same parts shown in Fig. '1, the brake being in operative position.

Fig. 3 is an end view of the carrier, the cable being shown in section, and the brake being in operative position.

Fig. 1 is a vertical sectional view taken on the line 41 of Fig. 1, the brake being in inoperative position.

Referring particularly to the accompanying drawing 10 represents a cable on which the carrier A is arranged to move, the said carrier being provided with the transverse shafts 12 and 13, on which are mounted the grooved wheels 14 and 15. Pivotally engaged with the outer ends of the shaft 13 are the ends of a pair of members or arms 16, the other ends being twisted into planes at right angles thereto and secured to the laterally directed arms 17 of a U- shaped member 18. A pair of parallel members have their ends turned outwardly, as at 19 and secured to the arms 17, said members being represented at 20, in the drawing. Between the other ends of the members 20 is mounted a grooved roller or wheel 21, the portions of the members 20, outwardly of the wheel 21, being flared or directed outwardly.

In the operation of the device, the members carried by the arms 16 are in the position shown in Fig. 1, wherein the grooved wheel 21 rests on the cable, between the wheels 11 and 15. The carrier can then be freely moved along the cable. When it is desired to hold the carrier against movement, the arms 16 are swung into the position of Fig. 3 so that the U-shaped member straddles the cable and exerts sufficient pressure thereon to prevent the rolling of the wheels 14 and 15 on the cable. Thus the carrier is held so that the load can be placed thereon, after which the arms 16 are swung over into the position of Fig. 1, with the wheel 21 in engagement with the cable, on which it will freely roll while the carrier moves along the cable.

Attention is called to the fact that the opening between the side portions of the U-shaped member is in the form of a wedge opening so that a wedging gripping action will take place between the cable and the side walls of the U-shaped member when the device is thrown into operative position. Thus the device is in effect a lock or chock to prevent any movement of the carrier while being loaded or unloaded.

What is claimed is:

1. The combination with a cable track and a carrier movable thereon, of a locking means for the carrier including a movably mounted member carried by the carrier and arranged to lie in gripping engagement with the cable at times and in rolling contact with the cable at times.

2. The combination with a cable track and a carriermovable thereon, of locking means for the carrier including a swinging cable at times and a roller for rolling c0nl) member mounted on the carrier and havlng tact with the cable at tunes.
